Sago Palm/ Cycasin

Sago Palm the most toxic of all bonsai trees. Sago Palm has Cycasin agents that are harmful to cats from the leaves to the stem. Their seeds are particularly the most dangerous - for both cats, little animals, and even little children. If you have a cat and you're considering buying a bonsai tree, my advice would be that you research for other feline-friendly species.

The rate of harm and fatality of Sago Palm upon ingestion is as fast as 15 minutes. If you grow Sago Palm as a bonsai tree, ensure to keep it out of the reach of pets by placing them in high places in the home. Other preventive measures like spraying cat repellents, e.g., lemon spray, keep them away from the plant.

Because Sago Palm is highly toxic to cats, any irritation sign should be considered. Some Sago Palm poisoning signs are Jaundice, tarry stool, depression, vomiting, lethargy, diarrhea, improper muscle function, fainting, tremor and seizures, reduced heart rate, slobbering, retching, ataxia, etc. Immediately you notice any of these signs in your cat, try to induce vomiting or rush the cat to the veterinarian for treatment.

Boxwood Bonsai Trees Ingesting a boxwood plant is not as fatal as when cats eat a Sago Palm. But the boxwood bonsai trees contain saps that can cause immediate skin and ultimately leads to lethal damage if ingested in large amounts. Do everything you can to keep your feline friend away from a boxwood bonsai tree. The boxwood bonsai contains a mixture of butter-like oil and alkaloids toxic to cats. The boxwood plant naturally tastes bitter. So, it should serve as a deterrent for cats. But all the same, it is wise to keep boxwood bonsai away from the reach of your cats. Some boxwood poisoning symptoms are skin discoloration, shallow breathing, rashness, irritation, etc.

Crassula argentea / Jade

The prolonged exposure of Jade Plants to pets could lead to poisoning risks. So it's wise always to check your Jade Plant to note any disorder in leave patterns, teeth marks as precaution measures. The Jade plants are "mildly" poisonous to cats but can be fatal if ingested in large quantity - or if early symptoms go untreated. Every part of a Jade Plant is bonsai toxic to cats. The early signs of jade poisoning are slow heart rate, vomiting, and reduced muscle functions. Please, seek a vet doctor immediately for treatment.

The Cherry Tree

Despite the beauty of cherry bonsai trees, their sap contains toxic cyanides harmful to cats. Every part of a cherry tree - leaves, stems, and root spreads - is made of poisonous cyanide chemicals. It should be kept away from cats. Because of the low concentration of cyanide on cherry trees, it takes ingesting it in large amounts for it to cause harm to cats. Some of the early signs of cherry poisoning are dilated pupils, improper breathing, lack of oxygen, and ultimately death - if no care is given to the cat.

Plum

Plums are good for humans because of our advanced body system. But they are particularly toxic to lower animals like cats. The whole plant is toxic to cats because it contains cyanide. But unlike cherry trees, the concentration of toxins in Plum trees is considerably low. And so, they're not so harmful when ingested by cats in low quantities. Keep your cats away from it and look out for early poisoning symptoms like vomiting, constant panting, breathing problems, etc.
